1730 ft higher than camp. Set traps at the base of the cliff on the way up; about 25 musk specials, almost all in muskroot at the base of the cliff. Huge rivers of muskroot (in flower) covering angular stones blocks - talus, a few specimens of "fig" tree, a few bushes. Near the top is another species of yellow dairy bush with crinkly rough leaves. Arrived at the top at 3 pm and within a few minutes about 8 condors soared over, some as close as 30 ft. - young, middle-aged, and adult - judging by white wing color. Weather overcast. They stayed aloft 1/2 hour, looking me over. Just as 3 or 4 of them had descented and the others were about to land, 100 goats were driven over the cliff only 50 yards from them, so they left. So did I. At least 8 or more were resting at the usual spot on the cliff. A few stars at sunset. yesterday when the geatherds were milling around the cliffs there were 20 condors in the air at one time. A large, long-tailed, black chimel, strafed these condors. lizard shot by Benson weighed 37 g. Nov. 10 bright overcast, and all morning. Traps in the musk-root at the base of the cliffs caught 1 musk and 4 ph. dermini. Grid caught 10 dermini. Marked more lizards on grid in a.m. although not quite warm enough or bright enough for large numbers, up to 8:10 a.m. had marked 21 individuals. Then went out again from 10:20 to 12:00 and cruised between each row. saw 20 lizards of which 5 were worked over = 2 x 20/5 = 84 individuals. Marked 6 of these so that as of noon today there are 27 marked individuals on the grid.
